FLUID-DZSIPLACJING APPARATUS.

Application filed May 26,

To all w/wm t may concern.'

Be it known that I, BENJAMiN SKnmoRE, Jr.. a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful improvements in Fluid-Displacing Apparatus, of which the following is a specification. y

This invention relates to improvements in fluid displacing apparatus, particularly adapted. though not necessarily limited in its use for creating a` suction or pressure, and one of the objects of the invention is to provide an improved apparatus ot this character embodying one or more rotors operating upon the liquid in such a manner that the slugs of liquid which are picked up by the rotor blades will be maintained substantially quiescent and will act stationary pistons and will be maintained in substantially an unchanged form or shape at all times while in the passages between the rotor blades, thereby obviating the dattening or breaking up of the liquid slugs.

To the attainment of these ends and the accomplishment ot other new and useful objects as`wil1 appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement of. the several parts hereinafter more fully described and claimed and shown in the accompanying drawings illustrating this invention and in which Figure l is a vertical longitudinal sectional view as taken on line A-L Figure 3.

Figure 2 is a sectional view taken on line B B, Figure l.

Figure 3 is a sectional view taken on line (l-C, Figure 2.

Figure 4 is an end elevation of Figure 5.

Figure 5 is a side elevation ot' one of the rotors- Referring more particularly to the drawings the numeral 34 designates a casing having a liquid inlet opening 35 and a discharge outlet opening 36.

rilhe casing may be ot' any desired size and configuration and is preferably provided with chambers 37-38 having communication with the interior of the casing.

assing through the casing and also through the chambers 37-38 is a shaft 39 which is mounted in suitable bearings 40-41 and the shaft also passes through suitable stuffing boxes 42-43, power being applied 1921. Serial No. 472,793.

to the shaft 39 from any suitableJ source and in any suitable manner.

Arranged within the chambers 37-38 are rotors 44-45 which are secured to the shaft 39 for rotation therewith in any suitable manner preferably by means of keys 46, and nutsl or collars 47, which engage threaded portions 48 on the shaft 39. rlhe rotors substantially fill the respective chambers 237-38 and are laterally spaced from each other, a suitable delector 49 being arranged in the space between-the rotors. This delector 49 may be of any desired size and configuration and held in position in any suitable manner so as to operate to deflect the fluid which is discharged from the rotors44-45, into the casing 34.

rlhe rotors 44-45 embody a body portion of any desired length and diameter and arranged ,about the periphery of the rotor 44 are blades 50--51 while blades :i2- 53 are arranged about the periphery ot the rotor 45. rthe blades of each rotor are arranged about the body .portion thereof, and are'laterally spaced from each other to forni fluid pas# sages therebetween and the blades terminate short of each other so as to for-m lateral discharge outlet openings 54-55 on theopposite sides of the delector 49 and in directions towards the deector and opposed to each other.

The blades of each rotor may he spaced from each other tor any desired. distance and the ends or portions 563-57-58-59 ot' the respective blades are arranged substantially concentric with the axis of rotation of the rotor and are substantially parallel, while the portions of the blades intermediate the said parallel portions are arranged spirally about the axis of rotation of the rotor. rlhe portion of the liquid confined in the passages between the blades will remain in a substantially quiescent condition with the result that as the rotor is actuated the walls of the passages will advance with respect to the liquid conlned in the passages,

until the spirally arranged portion of the blades operate upon the liquid to impart a lateral iow thereto towards the deflector 49.

During the operation of the rotor the inlets 61 ot' the passages between the blades will successively pass outlet openings (i2- 63 of passages 64 formed in the casing 34, and which passages 64 are provided with inlet openings 65 for admitting fluid into the mareas passages therebetween having lateral discharge outlets, the portions of proximate blades adjacent the outlets of the respective passages being substantially parallel and substantially concentric with the axis of rotation of the rotor whereby the liquid between the blades will be maintained in a substantially quiescent condition, the portions of the blades intermediate the said parallel portions extending spirally about the rotor in directions lengthwise of the axis ofthe rotor, the said rotors operating in opposition to each other.

6. An apparatus of thecharacter described embodying a casing having a liquid inlet and a discharge outlet,`laterally spaced rotors in the casing, and means forimparting a high speed of rotation to the rotors, each of said rotors embodying a plurality of blades extending .about the periphery of the respective rotors, the blades of each rotor being spaced laterally to form fluid passages therebetween having lateral discharge outlets, the portions of proximate blades ad'` the path of movement of the inlets of the jacent9 the outlets of the respective passages being substantially parallel and substantially concentric with the axis of rotation of the rotor whereby the liquid between the blades will be maintained in a substantially quiescent condition, the portions of the blades intermediate the said vparallel porj `tions extending spirally about the rotor in directions lengthwise of the axis of the rotor,

thesaid rotors operating in opposition to each other and alternately delivering fluid into the casing.

7. An apparatus of the character described embodying a casing having a liquid inlet and a discharge outlet, laterally-spaced rotors Vin the casing, means for imparting a high speed of rotation to the rotors, each of said rotors embodying a plurality ot' blades extending about the periphery of the respective rotors, the blades of each rotor being spaced laterally form fluid passages therebetween having lateral discharge outlets, the portions of proximate blades-adjacent the outlets of the respective passages being-substantially parallel and substantially concentric with the axis of rotation of the rotor 'whereby the liquid between the blades will be maintained ina substantially quiescent condition, the portions of the blades intermediate the said'parallel portions extending spirally about the rotor in directions lengthwise of the axis of the rotor, the said rotors operating in opposition to each other, and a delector interposed between the rotors and adjacent the path of movement of the outlets of the said passages for deecting the Huid in the casing. I

,8. An apparatus of the character described embodying a casing having aliquid inlet and a discharge outlet, a rotor mount# ed in the casing, means for imparting a high speed of rotation to the rotor, said rotorpembodyin a plurality of blades extending about t ie periphery of the rotor, said blades being spaced laterally to form-fluid passages therebetween having lateral discharge outlets, the portions of proximate blades adja-l cent the outlets of the passages being substantially parallel and substantially concentric with the axis of rotation, ofthe rotor whereby the liquid between the blades will be maintained in a substantially quiescent condition, the portions of the blades intermediate the said parallel portions extending spirally about the rotor in directions lengthwise of the axis of the rotor, and a conduit having one or more outlet openings adjacent said passages, the relative movement of the lsaid passages and the liquid therein operating to cause a suction in the said conduit.

9. An apparatus of the character described embodying a casing havin a liquid inlet and a discharge outlet, latera ly spaced rotors in the casing, and'means for imparting a' high speed of rotation to the rotors, each of said rotors embodying a plurality of blades extending about the periphery of the respective rotors, the blades of eachV rotor extending about the rotor in directions opposite to each other, the blades of each rotor being spaced laterally to form fluid passages therebetween having lateral dischar e outlets, the portions of proximate bla es adjacent the outlets of the respective passages being substantially `parallel and substantially concentric with the axis of rot-ation ot the rotor whereby the liquid between the blades will be maintained in a substantially quiescent condition, the portions of the blades intermediate the said parallel portions extending spirally aboutthe rotors in directions lengthwise of the axis of rotation of the respective rotors, the said rotors operating in opposition to each other. l
